The error message is generated by hmake, not by GHC, so the fault is
probably in the automatic configuration of the ghc settings in hmake.
I would guess that perhaps hmake has not detected ghc's version
number correctly?

Look in lib/ix86-OpenBSD/hmakerc, particularly for the definition

     cppSymbols = ["__GLASGOW_HASKELL__=504"]

and edit it if necessary.  (Of course, we'd really like to know why it
wasn't detected in the first place.)
